Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a foldable warning sign for use on construction sites. Background Art

[0002] The construction industry has always been a place where danger and safety coexist. If workers have low safety awareness and there are no other relevant personnel or warning signs on site to supervise and remind them, there is a great possibility of dangerous accidents.

[0003] For example, Chinese utility model patent publication number CN220933686U discloses a foldable sign. The improved sign features ventilation holes that can reduce oncoming wind, and a dust removal brush at the bottom of the sign not only removes dust from the surface but also acts as a counterweight to stabilize the overall center of gravity. Combined with the triangular structure at the bottom of the sign, it ensures that the sign is not prone to tipping over.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the foldable warning signs for construction sites in the related technologies are relatively large in size when in use, making it inconvenient for workers to carry them, thereby reducing the practicality of the device.

[0005] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0006] In order to solve the problem in the related art that the foldable warning sign for construction sites is large in size when in use, making it inconvenient for workers to carry it and reduce the practicality of the device, the present application provides a foldable warning sign for construction sites.

[0007] The present application provides a foldable warning sign for construction sites using the following technical solution:

[0008] A foldable warning sign for use on a construction site comprises two fixed legs arranged in parallel, a fixed rod is installed between the two fixed legs, the tops of the two fixed legs are rotatably connected to a warning sign via a rotating shaft, a limit assembly is provided on the fixed legs for limiting the rotation of the warning sign, and the rear sides of the two fixed legs are hinged with support legs, the limit assembly comprises a clamping column inserted through the interior of the fixed legs, the fixed legs are located on the outside of the clamping column and a sliding groove is provided, the interior of the sliding groove is slidingly provided with a slider fixedly connected to the clamping column, a spring is installed between the slider and the side wall of the sliding groove, and clamping grooves are symmetrically provided on both sides of the warning sign, and the clamping grooves cooperate with the clamping columns.

[0009] Preferably, connecting rods are rotatably mounted on the side walls of the supporting leg and the fixed leg, and the ends of the two connecting rods are fixedly connected by locking bolts.

[0010] Preferably, the end of the clamping column passes through the side wall of the fixed leg and is fixedly mounted with a pull plate.

[0011] Preferably, a handle is fixedly mounted on the bottom wall of the warning sign.

[0012] In summary, this application has the following beneficial technical effects:

[0013] 1. This application allows the warning sign to be rotatably mounted between two fixed legs via a rotating shaft. A slide groove, spring, slider, clamping column, and clamping slot are provided on the fixed legs. The warning sign can be rotated by pulling the clamping column away from the clamping slot. The clamping column is then released, allowing the clamping column to engage with the corresponding clamping slot, thereby folding the warning sign. This reduces the space occupied by the device and improves its portability.

[0014] 2. In this application, connecting rods are rotatably installed on the side walls of the fixed legs and the supporting legs, and the ends of the two connecting rods are fixed by locking bolts, so that the support angle of the supporting legs can be adjusted, thereby improving the stability of the device support.

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application discloses a foldable warning sign for a construction site, referring to Figure 1-3, including two parallel fixed legs 1, a fixing rod 11 is installed between the two fixed legs 1, the top of the two fixed legs 1 is rotatably connected to the warning sign 2 through a rotating shaft, a limiting component 3 is provided on the fixed leg 1 for limiting the rotation of the warning sign 2, and the rear sides of the two fixed legs 1 are hinged with support legs 4, the limiting component 3 includes a card column 31 inserted through the inside of the fixed leg 1, the fixed leg 1 is provided with a slide groove 32 on the outside of the card column 31, and a slider 33 fixedly connected to the card column 31 is slidingly provided inside the slide groove 32, and a spring 34 is installed between the slider 33 and the side wall of the slide groove 32, and card grooves 21 are symmetrically provided on both sides of the warning sign 2, and the card groove 21 cooperates with the card column 31.

[0021] Here, by pulling the card column 31, the card column 31 drives the slider 33 to squeeze the spring 34, so that it can move away from the card slot 21, and then the warning sign 2 is rotated so that the warning sign 2 can be rotated to the inside of the two fixed legs 1. Then, the card column 31 is released, and the spring 34 will restore its deformation, thereby pushing the slider 33 and the card column 31 to move and insert into the card slot 21, thereby limiting the folded warning sign 2, reducing the space occupied by the device and improving the portability of the device.

[0022] Reference Figure 1 A connecting rod 5 is rotatably mounted on the side walls of the supporting leg 4 and the fixed leg 1 , and the ends of the two connecting rods 5 are fixedly connected by locking bolts 6 .

[0023] Here, a connecting rod 5 is rotatably mounted on the side walls of the supporting leg 4 and the fixed leg 1 , and the two connecting rods 5 are fixed by locking bolts 6 , thereby facilitating adjustment of the angle between the supporting leg 4 and the fixed leg 1 .

[0024] Reference Figure 3 The end of the clamping column 31 passes through the side wall of the fixed leg 1 and is fixedly mounted with a pull plate 35.

[0025] Here, a pulling plate 35 is installed at the end of the clamping column 31, so that the clamping column 31 can be pulled to move.

[0026] Reference Figure 1 A handle 22 is fixedly mounted on the bottom wall of the warning sign 2 .

[0027] Here, a handle 22 is provided to facilitate carrying the device.

[0028] The implementation principle of a foldable warning sign for a construction site in an embodiment of the present application is as follows: when in use, first loosen the locking bolt 6 to open the support leg 4 to a specified angle, and then tighten the locking bolt 6 to place the device in the specified position. Thereafter, pull the pull plate 35, and the pull plate 35 drives the clamping column 31 away from the clamping slot 21, so that the warning sign 2 between the two fixed legs 1 can be rotated and opened. When the pull plate 35 is loosened, the spring 34 can push the slider 33 and the clamping column 31 to cooperate with the corresponding clamping slot 21, thereby limiting the warning sign 2 and completing the deployment of the warning sign 2; conversely, the warning sign 2 can be folded and then carried by the handle 22, thereby improving the portability of the device.
